Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

To control the flow of ferrous developer materialfrom a holding tank, an electromagnet is used to createa magnetic field which causes the material to alignitself in a manner so as to restrict the flow in adesired manner. In an electrostatic reproduction machine,a low power solid state device coupled with the machine

logic can be used to control the electromagnet. Pro-grainmed flow sequences are thus possible, making thepresent arrangement useful in an automatic developabilitycontrol system as disclosed in U. S. Patent No. 3,757,999for example.
